http://www.futurenet.org/18Commons/merkel.htm has: Are you treading lightly on the Earth or stomping around in size-22 clodhoppers? The answer is probably the latter, if you’re a North American. Compared to a person living anywhere else in the world, a North American consumes a far greater share of the Earth’s resources. But what about you? To measure the size of your own ecological footprint, take this test: Step 1: Calculate your resource use Step2: Multiply by the number of acres it takes to support that use {For my data sources, see notes below table. D.} Item/Your Use x Factor in Acres = Gas ___ gal/person(p)/month(m) x 0.12 = 0 Plane_____ hours/p/m x 1.45 = 0 Bus_____ miles/p/m x .001 = 4.3*12*.001 = 0.05 Veggies & fruit _____ lbs/p/m x .008 = 0.345*2.2*365/12 x .008 = 23.09*0.008 = 0.185 Grain, pasta, bread___ lbs/p/m x .023 = 0.37*2.2*365/12 x 0.023 = 24.76*0.023 = 0.57 Milk & yogurt_____ qts/p/m x .054 = 0.4226*365/12 x .054 = 12.855 x .054 = 0.695 Beef _____ lbs/p/m x .4 = 0 Poultry_____ lbs/p/m x .07 = 0 Meals out_____ # of meals x .09 = 0 Housing_____ sq-ft/person x .003 = 444 x .003 = 1.33 Electric use_____ kwh/p/m x .005 = 450/12 x .005 = 37.5 x .005 = .19 City gas_____ CCF/p/m x .04 = 0 Paper_____ lbs/p/m x .08 = 1 x .08 = .08 Plastic_____ lbs/p/m x .05 = 0 Electronics, phone, entertainment, insurance, appliances_____ $/p/m x .02 = 0 Education_____ $/p/m x .01 = 0 Garbage_____ lbs/p/m x .05 = .2 x .05 = .10 - {For daily quantities of foods, in graams: http://davd.tripod.com/MyDiet-inGrams.txt - {for Electricity, ~450 kWh: http://csff.colorado.edu/mail/pfvs/2001II/msg02345.html } - (Biggest part of the 3.2 acres is 1.333 acres: 3, in a 5-person 1250 sq.ft old house} Step3: Add the column on the right to estimate how many acres it takes to support you. Footprint estimate in acres = 3.2 (but actually less: no heating or cooling,) - - - - - - - - - - - - - - - ^^^ ( and very cheap 35-year-old construction.) Step 4 To find our how you stack up, compare your score with these average footprints (in acres per person): World Average - 7 Mexico - 6 China - 4 India - 2 Bangladesh - 1 United States - 24 Canada - 18 Russian Federation - 11 Shrinking the footprint disparity If the size of your ecological footprint reveals that you're currently using more than your fair share of the global commons, don't despair. Sustainability is still possible if we both reduce footprint disparity and have, on average, smaller families for 100 years. If you're one of the people whose footprint is too large, shrinking it will save you money and time. If your footprint is too small, increasing its size to move out of poverty will encourage you to have a smaller family. It's a win-win!
